BrainLAB uni-knee is intended to be an intraoperative image guided localization system to enable minimally invasive surgery. It links a freehand probe, tracked by a passive marker sensor system to virtual computer image space on an individual 3D model of the patient's bone, which is generated through acquiring multiple landmarks on the bone surface. The system is indicated for any medical condition in which the use of stereotactic surgery may be appropriate and where a reference to a rigid anatomical structure, such as the skull, a long bone, or vertebra, can be identified relative to a CT, X-ray, or MR-based model of the anatomy. The system aids the surgeon in accurately navigating a knee endoprosthesis to the intraoperatively planned position. Ligament balancing and measurements of bone alignment are provided by BrainLAB uni-knee.
Example orthopedic surgical procedures include but are not limited to:
* Unicondylar Knee Replacement
* Ligament Balancing
* Range of Motion Analysis
* Patella Tracking
Indications for use as stated in the FDA summary.
